Nitrogen balance and fate in a heavily impacted watershed (Oglio River, Northern Italy): in quest of the missing sources and sinks
We present data from a comprehensive investigation carried out from 2007 to 2010,
focussing on nitrogen pollution in the Oglio River basin (3800 km 2, Po Plain, Northern Italy).
Nitrogen mass balances, computed for the whole basin with 2000 and 2008 data, suggest a
large N surplus in this area, over 40 000 t N yr− 1, and increasing between 2000 and 2008.
Calculations indicate a very large impact of animal husbandry and agricultural activities in
this watershed, with livestock manure and synthetic fertilizers contributing 85% of total N …

We present data from a comprehensive investigation carried out from 2007 to 2010,
focussing on nitrogen pollution in the lower Oglio River basin (3800km 2, Po plain, Northern
Italy). Nitrogen mass balances, computed for the whole basin with 2000 and 2008 data,
suggest a large N surplus in this area, over 40 000 t N yr− 1, and increasing 5 between 2000
and 2008. Calculations indicate a very large impact of animal husbandry and agricultural
activities in this watershed, with livestock manure and synthetic fertilizers contributing 85% of …
